Found something similar in #64 but this issue is solved

If using ~/prebuilt_cdm_ios_widevine/shaka_plugin/dev_cdm.json, demo content plays without problem

As mentioned in the README of the CDM, you can't use the release CDM with a debugger. You can either not attach the debugger in Xcode, or launch the app manually without Xcode.

Sorry I missed this, thank for quick answer.

Btw. I also trying to figured out this older issue #175. I added more info recently with updated reproduction step to make it always happens. It cause app crash so till fix we can't use shaka embedded for production purposes. You didn't tag issue as Bug so I'm not sure if you recieved updated info so just for sure I wrote it here. Thanks
